Abstract: A sealing device between a rotor part and a stator part, including at least one abradable coating cooperating with at least two upstream and downstream labyrinth seal lips. Axially upstream of the labyrinth seal lips, the sealing device includes a circumferential wall that radially extends beyond the upstream free axial sealing surface of the coating to create, at the free end of the upstream labyrinth seal lip, a separation of the circulating gas.

Abstract: A rotor disc for a turbomachine, the disc extending circumferentially around an axis and including a plurality of cells configured to receive blade roots and each cell including an upstream radial wall configured to axially block the blade root in the cell, each cell being connected to an upstream surface of the disc by a ventilation channel of the cell, the ventilation channel including an inlet orifice which opens onto the upstream surface of the disc and an outlet orifice which opens into the cell. An assembly of such a disc, of a plurality of blades and of a downstream retaining ring and a turbomachine including such an assembly.

Abstract: A device for controlling the clearance between a rotor and a stator surrounding same, which is carried out by modifying the delivery flow carried in a rotor recess in order to provide a bleed flow that prevents the gases from the flow section from penetrating into the recess. A valve can partially close the delivery circuit, thus reducing the cooling of the rotor structure and allowing the expansion thereof and the reduction of the clearance with the stator, for certain operating speeds including cruise operating speeds. In addition, the delivery air is heated more at a lower flow rate, especially if it is made to follow a bypass provided with meanders in the hottest portions of the circuit.

Abstract: A sample holder for the measurement of nuclear heating in a nuclear reactor, comprises: a body configured to contain a heat-sensitive sample along a longitudinal axis; and means for removing heat from the body to the exterior of the sample holder, wherein the means for removing heat from the body to the exterior of the sample holder comprise: a peripheral structure located on the periphery of the body; and a central structure mechanically linking the body and the peripheral structure, the central linking structure being configured to transfer heat radially, i.e. perpendicularly to the longitudinal axis, between the body and the peripheral structure. A calorimeter cell for the measurement of nuclear heating in a nuclear reactor, comprises: at least one sample holder; a seal-tight casing in which the sample holder is placed; and temperature-measuring means.

Abstract: This concerns a sealing device between a rotor part and a stator part, comprising at least one abradable coating (46) cooperating with at least two upstream and downstream labyrinth seal lips. Axially upstream of the labyrinth seal lips, the sealing device comprises a circumferential wall (54) that radially extends beyond the upstream free axial sealing surface (48a) of the coating (46) to create, at the free end of the upstream labyrinth seal lip, a separation of the circulating gas.

Abstract: A boom assembly for a construction machine is disclosed. The boom assembly may have a first side barrier and a second side barrier spaced apart from each other. The first and second side barriers may have a first pin receiving groove and a second pin receiving groove, respectively. The boom assembly may have a boom including a pin receiving bore. The boom assembly may also have a boom mounting pin extending through the pin receiving bore, the first pin receiving groove, and the second pin receiving groove. Further, the boom assembly may have a first mounting member mounted on the boom mounting pin at the first pin receiving groove and being removably attached to the first side barrier. In addition, the boom assembly may have a second mounting member mounted on the boom mounting pin at the second pin receiving groove and being removably attached to the second side barrier.

Abstract: Linkage pins are commonly used to join two members to provide a rigid connection or to function as a pivot point. They are often manufactured from piece parts that ideally are provided with a protective coatings before assembly. The joint needs to be able to withstand the harsh environments linkage pins may be used in and the joining process must cause minimal disturbance to the coating to prevent it from having to be reapplied after manufacturing. The present invention discloses a method and linkage pin including a mechanical deformation to form a joint. The components are arranged in a particular orientation to provide optimum durability by aligning them in a direction dependent on the direction of the flexing caused by the forces acting upon the pin.

Abstract: An installation is provided for the wet treatment of textile materials disposed on material-carriers, comprising a tank with means for loading or unloading the material-carriers, a means for causing the treatment fluid to flow through said materials and, possible, a heat exchanger, each material-carrier having a box shaped base with an aperture for connection to an aperture of an adjacent material-carrier, or for connection to a first pipe of said fluid moving means which opens into a treatment volume so as to form a first fluid flow in one direction, the flow of said fluid in the other direction following a path which includes at least a second pipe of said fluid moving means also opening into said volume, this latter being limited laterally by walls extending between the floor and the vault of the tank and said first pipe and at least said second pipe each open into said volume through one or more passages formed in the vicinity of the floor of the tank.

Abstract: A method and installation are provided for the treatment in an appropriate apparatus of bodies of textile material introduced into and/or removed from the apparatus by means of a material carrier on which the bodies are loaded, the treatment such as washing, bleaching, dyeing or similar being carried out with a fluid flowing through the bodies in a circuit flowing in and out of the apparatus by the bottom thereof and established by matching sealing means provided on the carrier and the apparatus.

Abstract: A method and installation for removing water from, drying and/or conditioning fibrous, porous or filament materials. A stream of gaseous fluid is caused to flow through an enclosure, by means of a plurality of flow means, so that it passes through the materials to be treated under reduced pressure and/or with over pressure, from the inside towards the outside of the materials, or vice versa, and a stream of water vapor is caused to pass through said materials so as to accelerate the removal of water at the beginning of drying and/or to rapidly raise the temperature of the treated materials and/or to spray said materials, if desired, during drying.

Abstract: A machine for the liquid or gaseous treatment of textiles or other fibrous or porous materials, which comprises a partition (9) located in its end zone opposite its cover (2), which partition (9) forms, with the bottom of the machine (1) and the corresponding part of its side walls (14), a leaktight box which delimits an expansion zone for the treatment fluid, that part of the machine which is located between the cover (2) and the partition (9) forming the actual treatment zone (10), which accommodates at least one holder for the material, the machine further comprising a device for the circulation of the treatment fluid.
